Estimation Method for Radiated Noise Line Spectra of Underwater Moving-Target

LI Yao-bo, REN Zhi-liang, CHEN Guang (Dept. of Weaponry Engineering, Naval University of Engineering, Wuhan 430033, China)  
Based on the math model for radiated noise line spectra of underwater moving-target, the united estimation of radiated noise line spectra was realized by analyzing feature extraction of radiated noise line spectra of underwater moving-target. The feature of radiated noise line spectra of underwater moving-target was extracted by the united spectra estimation method based on the traditional and modern spectra estimation. Firstly, the power spectrum of gathered data was estimated respectively to get the image of power spectrum, and then, the image of power spectrum was analyzed, probable range of existential line spectra was defined, and the precise line spectra was recalculated.
